1 1 1 1 1 t 1 1 1 1 1 The NWS added ESP stream flow forecasting for the Cameo Gage during 1997. This capability was utilized in 1998 to help coordinate reservoir operations. Additional improvements to the extended forecast outlook were quite helpful and provide both improved and additional data for use in the ESP model. Finally, improved communications among all reservoir operators and water administration officials would help. Towards this end, the state of Colorado will be implementing the water administration tool as part of CRDSS in 1998. This tool will help distribute real time information concerning stream flows and reservoir operations to everyone as soon as it becomes available. The tool may be ready for use in 1998, but likely not until the runoff season is over. • Coordination with the Colorado Flood Task Force The Colorado Flood Task Force continually evaluates the flood potential around the state during the runoff season. The Task Force employees a private consultant (Henz-Kelly) to provide extended weather outlooks and also identify areas of potential flood threats. Alternatively, information on reservoir operations may useful to the Task Force. The exchange of information between the coordinated reservoir operations group and the Flood Task Force should be encouraged. In addition, the documentation of any flooding that may occur is of interest to both groups and coordination of this effort could help stretch limited financial resources farther. • Flood Warnings and "Pinch Points" on the River Affecting Coordinated Reservoir erations Several stream gages on the river have elevation levels identified on them at which flood warnings are issued. However, the State of Colorado and NWS do not always agree on what that elevation should be. The Coordinated Reservoir Operations Group would like to see one set of flood elevation levels identified for each stream gage upon which both the State of Colorado and NWS agree. "Pinch Points" are points downstream from each reservoir where flooding will occur first. These locations still need to be identified. IX. Recommendations The Coordination Committee has the following recommendations for future years: A. Conduct coordinated reservoir operations again in 1999 pursuant to the schedule outlined above. B. Continue working with the NWS Colorado River Basin Forecast Center to improve peak runoff forecasting. C. Continue to coordinate with appropriate parties on river administration and accounting issues. D. Work with the state of Colorado and NWS to identify high flow levels and locations potentially flooded or adversely affected by CROS. E. Initiate work with the state of Colorado and NWS to resolve differing flood stage levels or determinations at stream gages. 14
